MODULAR VALVED CONNECTOR FOR DRAINAGE SYSTEMS
Medical devices used to drain a cavity, such as a pleural space of a human body are disclosed. More specifically, the present disclosure relates to a modular valved connector used to connect a drainage catheter, such as a pigtail catheter, to a drainage system that includes a drainage reservoir or receptacle. The modular valved connector may be configured to include a male Luer lock connector.
1 . A modular valved connector configured to be coupled to a pigtail drainage catheter, comprising:
a valve housing;
a valve mechanism disposed within the valve housing; and
a connector portion configured to be coupled to an adapter of the pigtail drainage catheter.
2 . The modular valved connector of claim 1 , wherein the valve housing is configured to couple to a drainage system.
3 . The modular valved connector of claim 2 , wherein the drainage system comprises a valve actuation member configured to actuate the valve mechanism.
4 . The modular valved connector of claim 3 , wherein the valve actuation member comprises an external coupling mechanism.
5 . The modular valved connector of claim 3 , wherein the valve actuation member comprises a protrusion configured to compress the valve mechanism.
6 . The modular valved connector of claim 3 , wherein the valve actuation member comprises an elongate tube configured to pass through the valve mechanism.
7 . The modular valved connector of claim 1 , wherein the connector portion comprises an internally threaded collar or a male Luer lock connector.
8 . The modular valved connector of claim 1 , further comprising a secondary valve mechanism and a semipermeable membrane, wherein the semipermeable membrane is permeable to gas and substantially impermeable to bodily fluid.
9 . The modular valved connector of claim 1 , wherein the connector portion is configured to be sealingly coupled to the adapter of the pigtail drainage catheter.
10 . The modular valved connector of claim 1 , wherein the valve mechanism is configured to prevent fluid flow when in a closed state and to allow fluid flow when in an open state.
11 . The modular valved connector of claim 1 , wherein the valve mechanism comprises one or more of a one-way flow valve, a positive pressure release mechanism, a negative pressure release mechanism, and a suction regulator.
12 . A pleural cavity drainage system, comprising:
a pigtail drainage catheter comprising an adapter disposed adjacent a proximal end;
a modular valved connector, wherein the modular valve comprises:
a valve housing;
a valve mechanism disposed within the valve housing; and
a connector member configured to couple the modular valved connector to the adapter; and
a drainage system configured to be coupled to the modular valved connector.
13 . The pleural cavity drainage system of claim 12 , wherein the connector member is configured to sealingly couple to the adapter.
14 . The pleural cavity drainage system of claim 12 , wherein the connector member comprises an internally threaded collar and a tubular protrusion surrounded by the internally threaded collar.
15 . The pleural cavity drainage system of claim 12 , wherein the drainage system comprises a coupling member configured to couple the drainage system to the modular valved connector and to actuate the valve mechanism.
16 . The pleural cavity drainage system of claim 12 , wherein the connector member comprises a male Luer lock connector and the adapter comprises a female Luer lock connector.
17 . The pleural cavity drainage system of claim 12 , wherein the modular valved connector further comprises a secondary valve mechanism and a semipermeable membrane, wherein the semipermeable membrane is permeable to gas and substantially impermeable to bodily fluid.
18 . A method of draining a pleural cavity, comprising:
coupling a modular valved connector to an adapter of a pigtail drainage catheter;
coupling a drainage system to the modular valved connector; and
applying a negative pressure to the drainage system.
19 . The method of claim 18 , wherein coupling the drainage system to the modular valved connector comprises actuation of a valve mechanism.
20 . The method of claim 18 , further comprising drawing fluid from the pleural cavity and collecting the fluid in the drainage system.
